The first Pope, Simon Peter, was married. Jesus healed his mother-in-law.
The Catholic Church allows married priests in the Eastern Rites, but an issue often raised is who provides for their families? Other Apostles were married, but the fate of their families left behind as they met their martyrdom isn’t recorded.
Because some rites allow it, there is no one position by Rome, but a look at the early twentieth century upheavals supports the case for celibate priests. While many Catholic priests could meet martyrdom because wives and children couldn’t be used to coerce them, married clergy in other faiths were compromised by those relationships.
